Prior to 1.10.5, yourls_get_request() extracted the request path without sanitization, after which yourls_sanitize_url() and yourls_esc_url() preserved dot and slash traversal sequences before an attacker-controlled keyword reached file_exists() and include() under YOURLS_PAGEDIR. An unauthenticated remote attacker could traverse outside the intended pages directory and include a local PHP file that was already present on the server, such as an uploaded or injected file, causing the file to execute in the YOURLS web process. This issue is fixed in version 1.10.5.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","score":5.3},"cwes":["CWE-98"],"references":["https://github.com/YOURLS/YOURLS/commit/4e85972160a96e03a419a442d5bd8f21f2f02ddb","https://github.com/YOURLS/YOURLS/pull/4142","https://github.com/YOURLS/YOURLS/releases/tag/1.10.5","https://github.com/YOURLS/YOURLS/security/advisories/GHSA-f8ff-652m-j5rx","https://github.com/YOURLS/YOURLS/security/advisories/GHSA-f8ff-652m-j5rx"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:59:28.494260111+00:00"},"epss":{"cve":"CVE-2026-62858","score":0.00468,"percentile":0.40258,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
